Not working: Installing Beryl on Feisty Fawn w/ATI Radeon Card

I'm having a problem with this HowTo. I have the same video card specified by the author, and install of everything actually goes fine without an error. I can even start Beryl and get the little red gem in the top right of my screen. The problem is that it simply does not work. There are no 3D animations at all.

I right-click on the gem and goto "Select Windows Manager" and Metacity (Gnome Window Manager) is selected. I select Beryl, everything flickers for a second or two and then come back. I go back to "Select Windows Manager" and Metacity is still selected.

I've even tried the login where I choose Beryl at login. Beryl loads, and "Windows Manager" is even added to the load bar where it wasn't previously. Still, no 3D effects. I go to "Select Windows Manager" and still Metacity is selected. The same thing happens when I attempt to switch it Beryl again...

Alright. Bare with me here. It doesn't look like AIGLX is the problem. I think that may have been self inflicted with screwing around to get this working. Upon rebooting everything still seems to be in order, but Beryl still crashes and reverts to Metacity immediately:

Then I open Beryl Manager and select Beryl and my window manager. Same thing happens... ie flicker. When I go back in to check my Window Manager, sure enough Metacity is selected again due to Beryl crashing.

I'm not sure if this helps, but I tried to select Compiz as well. That will stay open, but everything goes to hell. I loose the top name bar of all my windows and the right side of my top menu bar and task bar disappears. When I drag the windows and they go into their 3d effects, it leaves a trail that doesn't go away. The top menu bar locks too, so I can't right-clock the red gym icon to turn it off. I have to go in through Applications > System Tools > Beryl Manager.

When I turn on the 3D Effects that come with Feisty Fawn itself, I get similar behavior that I see when I select Compiz as my Windows Manager. Title bars disappear, the right side of the top menu bar disappears, etc. Wasn't sure if that points to anything specific.

Nothing that jumps out at me. Any particular search string I should try? I searched everything for video and beryl. Nothing jumped out. Nothing really jumped out period even after starting Beryl and having it crash on me then checking the logs immediately. Thanks.

I set my screen resolution to 1024x768 and I'm up and running. The bad part is that this resolution is horrible and I'd certainly need a cube of desktops to get anything done. Any idea on how to change my maximum texture size? I didn't see anything in Beryl Settings Manager. Thanks again!

I had the same problem.
The thing with texture size is that the computer grapic card runs out of memory. Therefore you can get your fullresolution but then you have to go down in depth. Therefore change depth to maximum 16 instead of 24 and go back to 1400x1050 and it will (probably) work!!!
